Modeling same-direction two-lane traffic for bridge loading

O'Brien, Eugene J. ; Enright, Bernard (Elsevier, 2011-07)

Many highway bridges carry traffic in two same-direction lanes, and modeling the traffic loading on such bridges has been the subject of numerous studies. Different assumptions have been used to model multiple-presence ...
Simplifed site-Specific traffic load models for bridge assessment

Getachew, Abraham ; O'Brien, Eugene J. (Taylor & Francis, 2007-12)

Traffic load is identified as one of the greatest sources of uncertainty in the assessment of bridges. In recent years, simulation techniques, using measured traffic data, have been used to predict the characteristic traffic ...
Traffic load modelling and factors influencing the accuracy of predicted extremes

O'Connor, Alan ; O'Brien, Eugene J. (NRC Research Press, 2005-02)

Design and assessment of highway bridge structures requires accurate prediction of the maximum load effects, i.e. shear forces and bending moments etc., which may be expected during the proposed or remaining life of the ...
